DESCRIPTION & OPERATION
The Duct Booster

RB-Series Register Booster fans are designed to increase the flow of heated air in warm air heating systems or
cooled air in central air conditioning systems. The ultra-quiet Register Booster fans are ideal when the duct run serving the room is not
accessible to install a standard Tjernlund In-Line Duct Booster
®
fan. Plugs into a standard 115 VAC outlet. Control with built-in on/off
switch inside register or use a remote on/off switch or programmable timer, available from most do-it-yourself hardware stores. Optional
SCP speed control is also available from Tjernlund if desired.
